Wireless Emergency Alerts, formerly known as Commercial Mobile Alert System (CMAS), e.g. earthquake or tsunami alerts.
When a phone receives the WEA signal (alert) how does Android system consume it? Is it a regular alert dialog, or a system notification? How does it bypass the ringer?
If I can trigger a system notification programatically with NotificationCompat package from support library, or a classic Alert Dialog, then how can I "create" emergency alert?
I would like to test it locally on a few devices to see the difference between them.
